Definitions

  • the present invention relates to an ink vessel which is suitable when a residual amount of a colored liquid ink has to be sometimes confirmed visually in uses in which an ink regardless of water soluble and oil soluble is fed from vessels, such as a writing tool in which an ink is directly used in the form of a liquid, an ink container employed when an ink is used for a printer in the form of ink jet and an ink reservoir employed when a liquid ink is used directly for a recorder.
  • Sho 38-7326 are known, though they do not intend to provide the ink reservoirs with visibility for residual amounts of colored liquids, as those in which projected grooves are provided on circumferential wall faces in the cartridges for a purpose to ensure flow-down of ink when fountain pens are turned into a use state in which pen points of the fountain pens are held downward from a non-use state in which the pen points are held upward, particularly when a residual amount of the ink decreases.
  • all of them intend to cause an ink stored in the reservoirs to flow down surely and quickly by vertical dislocation of the ink reservoirs and do not have a purpose to provide the ink reservoirs with visibility for a residual amount of an ink.
  • An object of the present invention is to provide an ink vessel which is suitable when a residual amount of a colored liquid ink has to be sometimes confirmed visually in uses in which an ink regardless of water soluble and oil soluble is fed from vessels, such as a writing tool in which ink is directly used in the form of a liquid, an ink container employed when the ink is used for a printer in the form of ink jet and an ink reservoir for a recorder.
  • the present invention relates to:
  • Fig. 1 is a horizontal cross section of the vessel of the present invention in which a plurality of semi-cylindrical projections are provided in the inside thereof.
  • Fig. 2 is an elevation seen from an A-A line cross section in Fig. 1. Codes in Fig. 1 and Fig. 2:
  • inks having extremely low surface tensions unlike conventional inks have come to be used as a water base ink in many cases according to a progress in a surfactant. Further, not only water base but also various solvent base solutions have come to be used as a solvent or a dispersion medium for a colored liquid such as an ink in many cases.
  • An object of the present invention is to provide a ink vessel which is suitable when a residual amount has to be visually confirmed in a vessel such as an ink vessel for a jet printer and an ink reservoir for a recorder as well as an ink bottle in correspondence to a diversification in surface tensions of liquids and vessel walls.
  • the present invention relates to a vessel provided with visibility for a residual amount of a colored liquid, wherein plural lines of ridge-shaped transparent projections having a cross section showing a domed curve are disposed parallel at intervals in the inside of a transparent vessel containing an opaque liquid in a direction in which a residual amount of the liquid has to be confirmed.
  • the domed curve is a curve having an almost semi-circular, circular arc-shaped, parabolic or semi-cylindrical cross section.
  • the present invention relates to the vessel provided with visibility for a residual amount of a colored liquid as described above, wherein the ridge-shaped projections are semi-cylindrical; and when the colored liquid is of an aqueous base, a radius (R) thereof falls in a range of 0.15 to 1.5 mm, and intervals at which the projections are disposed parallel fall in a range of 0.4 to 2.0 mm in terms of an intersectional interval of the semi-cylindrical projections with the inner wall of the vessel.
  • the present invention relates to the vessel provided with visibility for a residual amount of a colored liquid as described above, wherein the ridge-shaped projections are semi-cylindrical; and when the colored liquid is of a polar or non-polar organic solvent base, the radius (R) thereof falls in a range of 0.25 to 1.0 mm, and intervals at which the projections are disposed parallel fall in a range of 0.8 to 1.0 mm in terms of an intersectional interval of the semi-cylindrical projections with the inner wall of the vessel.
  • Suitably used for materials for the ink vessel are at least one selected from the group consisting of an acryl base resin, a styrene base resin, a polycarbonate base resin, a polyester base resin, a polypropylene base resin, a polyethylene base resin and a polyallylate base resin when the liquid is of a water system, at least one selected from the group consisting of a polyester base resin, a polypropylene base resin, a polyethylene base resin and a polyamide base resin when the liquid is of a polar organic solvent system, and at least one selected from the group consisting of a polyethylene base resin and a polyamide base resin when the liquid is of a non-polar organic solvent system.
  • a colored liquid layer flows down on the surface of the cylinder more rapidly than an inner wall face part in the vessel by providing semi-cylindrical transparent projections having a cross section showing a domed curve shape in the inside of the vessel.
  • a transparent semi-cylindrical column plays just a part of a semi-circular lens to form one transparent line in a semi-cylindrical column direction. Accordingly, it is a matter of course that the semi-cylindrical column does not have to be strictly semi-circular, and it can be a semi-circular column.
  • the radius (R) of the semi-cylindrical column is effective in a range of 0.15 to 1.5 mm.
  • the radius (R) of the semi-cylindrical column is effective in a range of 0.25 to 1.0 mm in both of a non-polar solvent system and a polar solvent system.
  • the narrow interval between the semi-cylindrical projections increases a power for holding a colored liquid such as ink in a dent formed in an intersectional part of the semi-cylindrical columns with the vessel wall, and the colored liquid held in this part narrows an area of the semi-cylindrical column and reduces an amount of transmitted light. Accordingly, the quick and easy visibility can not be expected.
  • the too large interval makes no difference from the vessel wall itself and causes an effect as a bundle of transparent lines which contributes to the visibility to be lost.
  • the ranges in which the interval between the semi-cylindrical columns is effective are 0.4 to 2.0 mm in the water base and 0.8 to 1.0 mm in the oil base.
  • the vessel does not have to be cylindrical and shall not be restricted thereto. Even if the vessel is curved, it shall be sufficient that the semi-cylindrical columns are held in a face parallel to a required direction and the plural lines are disposed parallel to the face described above.
  • Fig. 1 Shown in Fig. 1 is a horizontal cross section showing the plural semi-cylindrical projections 1 of the present invention provided in the inner face of the cylindrical ink reservoir 3.
  • the numeral 2 shows an intersection interval of the semi-cylindrical projections with the vessel wall.
  • Fig. 2 is an elevation seen from an A-A line cross section in Fig. 1 and shows the semi-cylindrical projections provided in the inner face of the ink reservoir.
  • An obliquely lined part 2 is the original inner wall of the cylindrical ink reservoir.
  • the use of the colored liquid vessel of the present invention has caused the visibility of the residual amount face of the liquid such as ink to be revealed very clearly even when a wettability of the vessel wall contacted has been changed to a large extent in the case where a surface tension of the liquid is extremely low and liquids other than water are used as a solvent or a dispersion medium or in the case where various synthetic resins other than glass are used for the vessel.
  • a radius R of plural semi-cylindrical projections provided in the inner face of an ink bottle molded from a transparent polypropylene resin (J-952 manufactured by Grand Polymer Co., Ltd.) was changed to 0.1, 0.15, 0.25, 0.5, 1.0, 1.5 and 2.0 mm, and the interval thereof was changed to 0.3, 0.4, 0.8, 1.0, 1.5, 2.0 and 2.5 to prepare the ink bottles.
  • the visibilities for residual amounts (level position) of a water base opaque liquid and polar and non-polar solvent base opaque liquids were determined, and the results thereof are shown in Table 1.
  • a water base opaque liquid ink (1), a polar solvent base opaque liquid ink (2) and a non-polar solvent base opaque liquid ink (3) each having the following composition were put into the ink vessels produced from the respective resins shown in Table 2 to test use aptitude of the respective water base, polar organic solvent base and non-polar organic solvent base liquids for the resins used for the vessels. The results thereof are shown in Table 2.
